damage to the membrane structure. Since catalase utilizes hydrogen peroxide as both an electron acceptor and donor it oxidizes hydrogen peroxide isolating oxygen while it simultaneously reduces the second hydrogen peroxide molecule to water2. The decomposition of hydrogen peroxide by the enzyme catalase is represented in the following balanced equation:2H2O2(l) 2H2O(l) + O2(g). Dead cells may still be studied to learn more about enzyme function because as seen in the liver despite the fact that the

Enzyme Lab: Peter Kuetzing – 10/4/2012 – F Block 1. How does changing the concentration of enzyme affect the rate of decomposition of H2O2? When more enzymes is added the rate of reaction speeds up. In this case‚ H2O2 will produce more O2‚ in return the kpa/min will go up. 2. What do you think will happen to the rate of reaction if the concentration of enzyme is increased to five drops? Predict what the rate would be for 5 drops. I think that the rate of reaction will slightly increase from

PREDICTION: A prediction that can be made for this experiment is that the higher the concentration‚ the faster time it takes the catalase to react with the solution. As the concentration increases from
